Abstract
We study the interface between Regge behavior and DGLAP
evolution in a non-perturbative model for the nucleon structure
function based on a multipole pomeron exchange. This model
provides the input for a subsequent DGLAP evolution that we
calculate numerically. The soft input and its evolution give a
good fit to the experimental data in the whole available range of
x and
Q2.
